We have always believed that male infertility is caused by too weak sperm, but research has found that too strong sperm in men can also lead to infertility. What's the matter?
According to the Daily Mail of England, one in six couples in the UK cannot conceive successfully every year, and about 35000 women need to become mothers through in vitro fertilization. After studying, evolutionary biologist Oren Hasen of Tel Aviv University in Israel believes that there is a significant relationship between this and male sperm. Just the stress of life, the impact of disease, and environmental pollution are not enough to explain the high infertility rate in men.
He infers that the reason for some male infertility is that there are too many sperm and their vitality is too strong. These brave "elite soldiers and powerful generals" together crossed the defense line leading to the egg, causing the phenomenon of "multiple sperm entering the egg", seriously interfering with the normal fertilization process of the egg.
Professor Hasen pointed out that during the long evolutionary process, the reproductive systems of men and women have been undergoing subtle changes. The female reproductive system has strengthened its defense ability against sperm, while the male sperm is also continuously cultivating "internal skills" to penetrate the female defense line with greater vitality. "If the evolution of both sexes is in step, the success rate of fertilization will increase, and conversely, problems will arise. Whether it is excessive or insufficient sperm, it can make it difficult for a woman to conceive.".
